METHOD AND DEVICE IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2015 - IPC G06F1/12 H04W56/00 

FIELD: radio engineering, communication.

SUBSTANCE: present invention relates to a wireless communication system and is intended to determine time synchronisation shift between radio base stations. A time synchronisation method comprises receiving, from a first radio base station, a first time advance value used by user equipment to control transmission timing thereof before handover and measure random access preamble reception timing. The random access preamble is transmitted from the user equipment to a second radio base station during synchronisation. The method also comprises receiving, from the second radio base station, a second time advance value used by the user equipment to control transmission timing thereof after handover, and determining time synchronisation shift between the first and the second radio base stations based on the received second time advance value, second time advance value and reception timing measurement.

EFFECT: high accuracy of time synchronisation.
